This research aimed at generating and evaluating prediction equations to estimate metabolizable energy values in poultry offal meal. The used information refers to values of apparent and true metabolizable energy corrected for nitrogen balance (AMEn and TMEn) and for chemical composition of poultry offal meal. The literature review only included published papers on poultry offal meal developed in Brazil, and that had AMEn and TMEn values obtained by the total excreta collection method from growing broiler chickens and the chemical composition in crude protein (CP), ether extract (EE), mineral matter (MM), gross energy (GE), calcium (Ca) and phosphorus (P). The general equation obtained to estimate AMEn values of poultry offal meal was: AMEn = -2315.69 + 31.4439(CP) + 29.7697(MM) + 0.7689(GE) - 49.3611(Ca), R² = 72%. For meals with high fat contents (higher than 15%) and low mineral matter contents (lower than 10%), it is suggest the use of the equation AMEn = + 3245.07 + 46.8428(EE), R² = 76%, and for meals with high mineral matter content (higher than 10%), it is suggest the equations AMEn = 4059.15 - 440.397(P), R² = 82%. To estimate values of TMEn, it is suggested for meals with high mineral matter content the equation: TMEn = 5092.57 - 115.647(MM), R² = 78%, and for those with low contents of this component, the option is the equation: TMEn = 3617.83 - 15.7988(CP) - 18.2323(EE) - 96.3884(MM) + 0.4874(GE), R² = 76%.

Forest rangelands contribute largely to goat diets in the Mediterranean area. Information about browsed plant quality is essential for adequate feeding management. The purpose of this study was to evaluate the temporal changes in chemical composition and in vitro digestibility of the main plant species selected by goats in the Southern Mediterranean forest rangeland during two consecutive years; these were very contrasted (dry and wet). The browsed species were composed of herbaceous, eleven shrubs, and four tree species. Overall, large variability in chemical composition, in vitro organic matter digestibility (IVOMD), and metabolizable energy (ME) was observed among species, grazing season (spring, summer, and autumn), and years within each species. Crude protein (CP) content varied from 60 to 240 g/kg dry matter (DM). The fiber fractions, except for Quercus suber, increased significantly by advancing maturity. Due to the water stress, the lignin level presented a higher value during the spring of the dry year. Condensed tannin (CT) content varied from 2 to 184 g/kg DM. CP, IVOMD, and ME showed a negative correlation with lignin and CT. Based on the results presented herein, it is concluded that the nutritive value of the browsed plant species was highest in the spring and lowest during the summer and autumn of both studied years. With a good grazing management strategy, the selected plant species by goats could guarantee high-quality feeding resources throughout the year.

Twelve pea cultivars (yellow-, green- and brown-seeded) were evaluated for chemical composition and digestibility in poultry. The evaluation involved analyses for protein, amino acids (AAs), fat, starch, dietary fibre, ash, calcium, phosphorus and tannins. True metabolizable energy [nitrogen corrected (TMEn) and uncorrected (TME)] and true AA bioavailability values were also determined with adult cockerels. The cultivars showed a wide range of protein (207.5–264.0 g kg−1) and starch (385.3–436.8 g kg−1) contents which were not related to the seed coat colours. The concentrations of several AAs varied among the cultivars. With the exception of arginine, the concentrations of all other essential AAs on a protein basis decreased as protein levels increased. Out of 10 essential AAs including cystine, only arginine had a positive correlation (r = 0.79) with protein content. The dietary fibre contents varied between 190.7 and 223.1 g kg−1 and the values were slightly higher in the brown-seeded cultivars. The brown-seeded cultivars contained appreciable quantities of tannins, while the yellow- and green-seeded cultivars were devoid of tannins. The cultivars were almost devoid of fat and calcium but relatively high in phosphorus. Starch and dietary fibre were negatively correlated with protein content (r = −0.78 and −0.46, respectively), and accounted for the greatest difference in protein content. The TME values ranged from 11.6 to 13.3 MJ kg−1 while the TMEn values ranged from 11.0 to 12.9 MJ kg−1. The mean availabilities of AAs ranged from a high of 89.6 to a low of 75.9%, with total sulphur AAs (cystine and methionine) having the lowest value and glutamic acid having the highest value. There was a trend (P ≤ 0.05) towards lower AA bioavailability values in the brown-seeded cultivars. It can be concluded that these cultivars varied in chemical composition, metabolizable energy content and bioavailability of AAs. Key words: Field peas, composition, digestibility, chicken, poultry

Sorghum Grain

Metabolizable energy assays using Australorp chickens were carried out on sorghum and maize hybrids grown in different regions in Queensland and harvested in different years. Relationships between metabolizable energy and the chemical composition of the grains were examined. Some comparisons also were made between the energy metabolized by different strains of chickens. The mean nitrogen-corrected metabolizable energy values and standard deviations for all maize and sorghum grains were 3770 � 154 (n = 48) and 3750 � 239 (n = 39) kcal per kg dry matter, respectively. There were significant differences in metabolizable energy values between locations and years of harvest for both grains. Significant differences were seen between sorghum hybrids, but not between maize hybrids. The interactions, hybrid x region and hybrid x year, also were significant for sorghum. Correlations between metabolizable energy and chemical composition of the grains were not sufficiently high to enable metabolizable energy to be predicted with the accuracy necessary for practical application. Chickens from a White Leghorn and two commercial broiler strains gave similar metabolizable energy values to those obtained with the Australorp chickens.
